These are warnings rather than errors, and have been happening in the PHP sample for a while, depending on what call you are making and what data is being returned. It appears that the two warnings that you posted are retrieving lists from your account, as well as any 'links' contained in the lists collection (link to the next page of lists perhaps). This should not however prevent any functionality from completing as they are not fatal errors. Typically, I would recommend that you turn error messaging off in a production enviornment anyway which can be done by using:
error_reporting(0);
at the top of you page. You can also set this globally in your php.ini file.
As our API's have not been updated, If your error message settings are the same in your development or production environments, then the change must be the account data being returned. If this is not adding any contacts to your account, I would need to see:
1) your account name
2) an example email address that is not being added
3) the code you are using to add the contact.
You can either reply to this thread with that information, or send it over to our webservices team, and we'll be happy to take a look. Thanks!
